To all whom it may concern:

Be it known that I, JOHN L. ALLEN, a citi-I This invention relates to improvements in.

machines for fitting and fastening can heads to can bodies and refers more specifically to mechanism for crimping the flanges of the can heads upon the can body, and to improvenientsin a combined can-heading and crimping machine.

The invention consists in the matters hereinafter set forth and more particularly pointed outin the appended claims.

Fig. 14 isawertical section, taken on line 14-14 of Fig. 2. Fig. 15 is a partial end view of the machine, showing means for feeding can heads and bodies thereto. Fig.

16 is a partial sectional view illustrating chutes for feeding canheads and, bodies to the machine, and also the means'gfor interinittently rotating the carrier by .tvhich the by the crimping mechanism.

can bodies are brought successively into operative relation to'the heading and crimping mechanisms.

As shown in the drawings, A designates the hollow cast-metal base of the machine, which is made of box-like form, as more clearly indicated in Figs. 1 and 12 to 14 inclusive, and B the main driving shaft having suitable bearing in said base and rovided at one end with a belt wheel B. he machine herein shown embraces a carrier C by which the can bodies are received and in which they are successively carried to the heading and crimping mechanisms and in which they are held during the operation of the heading and crimping mechanisms. The carrier consists ofa rotative wheel, shown more clearly in Figs. 2, 15 and 16, having peri heral depressions c to receive the can odies and is mounted on a horizontal shaft C that has intermittent rotative movement, as hereinafter described. The said carrier is located between the opposing, oppositely actuated parts of the can heading and crimping mechanisms, as more clearly seen in Fig. 2.

The carrier is so disposed, relatively to the heading and crimping mechanisms as to hold one can in position to be operated upon by the heading mechanism, while the next can in advance is in position to be operated upon I The heading and crimping mechanisms are located vertically one over the other, as shown in Figs. 4

and 5, wherein D designates, as a whole, (Figs. 3 and 4), the heading mechanism and E designates, as a whole, the crimping mechanism. A suitable curved guide C is located in front of and over the carrier to hold the can bodies in the depression 0 while being delivered to the can heading and crimping mechanisms. Said uide is fastened, as herein shown, to the eed chute C by which the can bodies are fed to the depressions in said carrier. The body chute C is supported on an arm A rising from the machine base.

Inasmuch as the two sets of opposing heading mechanisms are essentially alike, the following description of said mechanisms, for sake of clearness, will refer to a single set or a single side of the machine. The oppositely acting parts of the heading mechanism are carried heads D D which have sliding engagement with the base A, said cross-heads being proby two oppositely located crossllU operative parts of the heading mechanism body when the heading mechanism is forced are mounted. The cross-head is formed at its lower side to constitute laterally extending flanges 41' which have sliding engagement with suitably disposed, horizontal channels ism, are mounted in depending heads Ff of said cross-heads (Figs. 2 and 5) which, as

herein shown, are made separate from and are attached to the main parts of the heads by means of vertical bolts c c. The means for operating said cross-heads to move them towards and from each other are made as 1 follows:

Each cross-head is provided at its outer end with a large lug F rising therefrom. F designates a horizontal operating rod which is pivoted at its inner end to a pin f extending transversely across a. recess formed in the outer face of said lug, and said operating rod is operatively connected with a vertically swinging cross-head cam lever F 2 that is pivoted to a bracket A on the base and is 0perated at its lower end by a suitable cam F mounted on the main power shaft B outside of the end wall of the base A. The outer end of the bracket A constitutes a bearing for that part of the'power shaft which extends beyond said hollow base. Means are provided for varying the distance apart of the heading and crimping mechanism to accord to the length of cans of varying lengths. As herein shown, this adjustment is effected by making each operating rod F of two parts, it comprising an outer screw-threaded section f which has screw-threaded engagement with the inner pivoted end thereof, and has screw-threaded engagement also with a nut f that is loosely carried by the upper end of the lever F and which constitutes a connection between said cam lever and rod. The lower or depending end of the cross-head, which carries the crimping mechanism, is provided with a vertical extension e that is forked at its lower end and fits over a sleeve 1) encircling and non-rotatively mounted on the power shaft, (Fig. 2). Said sleeve moves endwise on the shaft when the cross-heads move in their ways, and itcarries some of the actuating cams and gear wheels of the mechanism, as will hereinafter more fully ap ear.

Referring now to the construction 0' the heading mechanism,- w hereby the can heads or ends are fined 10 the bodies preparatory to the crimping mechanism, these parts are made as follows:"l"he iLCtlVC parts of each heading mechanism embraces, in general terms, a chuck adapied to receive and hold towards said body. Each hall'ol' the heading mechanism embraces, in its construction a chuck sleeve l contained Within the cvlindric bore of the part l)" of the cross-head.

and said sleeve is provided with longitudinal slits (1 (Figs. 4 and 5). three being herein shown, the inner ends of which constitute lingers which are -apable of being pressed together to close upon a can head. I) designates a closing sleeve closely surrounding the chuck sleeve and carrying at its inner end a wedge or closing ring (1. Said wedge ring (1 is provided with an annular wedge or tapered surface (1 which engages complementally inclined exterior surfaces at the inner end of the split closing sleeve (Fig. 3 When the closing sleeve and wedge ring are. moved inwardly relatively to the chuck sleeve by the means hereinafter described, the inclined surface of the ring (I acts to press together or close the fingers or split portions of the chuck sleeve upon a can head contained therein. The said chuck sleeve is held in place in the cross-head by means of .an exteriorly screw-threaded locking ring (Figs. 3 and 4) which has screw-threaded engagement with the inner end of the hollow cylindric part of said cross-head. Said ring surrounds the extreme inner end of the chuck sleeve, and abuts at its outer end against an inwardly facing shoulder (1 formed on said ring, (Fig. 3). Said locking ring is turned in lace by means of a spanner engaging suitab e spanner holes (Z of the ring (Fig. 4). The segments of the facing ring are fastened to the chuck sleeve by means of screws (Z Thechuck sleeve is made larger than the. largest can head to be operated upon and is provided with a re movable facing ring made' up of as many separate segments as there are parts or tingers of the chuck sleeve (Figs. 3 and 4), a number of different sizes ofsets of said face rings are provided to provide for can heads of different diameter. The largest; size facing ring is shown in Fig. 3 and in order to opcrate upon smaller sized can heads, rings having thicker walls are provided. The closing ringd and. sleeve D are held normally in their retracted POSil ions, to permit the chuck to spring open. A spring D3 acts to hold the chuck sleeve outwardly against the locking ring (1. The said facing ring is flared at its outer side or margin to permit the same to readily pass over a can body. The ring is provided with an annular recess d"' (Fig. 3) in line w ith a receiving opening for said chuck designated, as a whole, by d downwardly through which the can 'heads are dropped into the chuck, the heads being received in said recess with their rims or flanges directed inwardly, as shown in said Fig. 3. Said recess is made of greater width the head in position to be forced on the can than that of the can head rim or flange. Be-

Cir

wardly carrying the chuck, and the backing through the medium tween the outer sides of said recess and the head is pressed inwardly until arrested by the annular stop d by means of a centrally located backing plate G that fits viithin the chuck sleeve and ring. T he plate is operated to reciprocate inwardly and outwardly of a stem G .in a manner hereafter described. The can heads are dropped into the chuckat a time when the backingplate G is retracted, as shown in Fig. 2, and thereafter the backing plate G moves inwardly to confine the headbetween said plate and the annular stop shoulder (1 Thereafter the cross-head is moved inplate ismoved inwardly at the same speed by its 0 crating mechanism, and in this manner the ead is forced on the can body, which latter is held in position to receive the head by the carrier (1 or other equivalent device. The can heads are fed to the admission openings orslits d. of the heading chucks through laterally separated chutes D D supported in any suitable manner on the frame of the machine and attached at their lower ends to the cross-heads as shown in Fig. 2. The head chutes are designed to be fiexiblyconnected with their supports at their upper ends (in amanner not necessary to be here shown) to permit the lower ends thereof to swing toward and from each other upon movement of the cross heads. Suitable controlling stops. are provided at the loner ends of said chutes D to hold the lower set of heads therein until the set last delivered therefrom are applied to the can body and until another body is in position to. receive a set of heads. As herein shon n, each controllin stop consists of ahar l) (Fi 2) pivoted to a stud (1 extending latera ly from the adjacent chute, and said vertical bar is provided at its ends ith horizontal stop pins d (1 adapted to alternately extend into the chute in the path of the beads by reason of the swinging movement of the bar U! The bar is adapted to he svv ung on its pivot. As herein sho'nn, the can head stopint chani" in heretofore described is operated from the plunger stem G, the opera; tive C(HHWCUODR being as nates an arm rising from and fixed rigidly t6 said stem G. G" designates a rod which ex";- tends through an opening in the upper pa t if )ins which en a e follows: (i desig-j the upper end of said stud G" and is attached ing bar 1) of said can head stop device in such manner that during each backward and fornard reciprocation of the plunger, the controlling device is operated to permit one can head to he led from the chute and to allow another can head to drop into position to be fed therefrom in the next operation of the ma chine. ln order to prevent communication of abrupt movement from the end'wise movable plunger" stem (i' to said stop device, the stud (r is preferably connecthd by a spring or cushion connection with the rod G. This is effected in the present instance by placing spirall v', expansively acting springs g g betocen the upper end of said stud and collars g g adjustahly fixed to said rod G, as shown in Fig. 2.

The sleeve 1) carrying the vvedge or closing ring d is moved endnise in the hollow cylindric part I) of the cross-head through the medium of a cam I) fixed to the sleeve h, before referred to, and a vertically reciprocating lever l) \\hich is pivoted to a horizontal pin d" on the cross-head (Figs. 2 and 13), and is operativclv connected at its up- .per end with the linli r of an end plate (1 of said chuck closing sleeve 1). As herein shown, the upper end of the cam lever is forked and is provided pith inwardly extending pins d engaging an annular groove in a nut fitting over and having screwthreaded engagement vvith said hub (Figs. 2 and 13). Said screw-threaded connection admits adjustment of the closing wedge or ring relatively to the chuck.

The stem G of the backing plunger G is operatively connected nith and actuated by a cam G fixed to the pen er shaft B; whereby said plunger or plate is moved inwardly and outlxvardly at the proper times. Said stem G is guided in its reciprocatory movement by the hub of the chuck actuating sleeve and the upwardly projecting lug F of the crosshead D, as clearly shown in Fig. 2. The operative connection lretneen the said power shaft B and the cam G consists of a vert ie ally swinging cam lever G inch is pivoted to a cross-pin 9 fixed to the ltraelwt A of the mm chine base, The lever G (ngagrs a suitably shaped peripheral groove on the cam G" and is forked at its upper end and provided n ith an annular groove in a nut 9* that has screw-threaded engagement ith said stem G. Said screw-threadul' connection affords adjustment of the plate (1 relatively to the other parts of the heading chuck.

Before proceeding with the description of the crimping mechanism. brief reference will be made to the operation of the heading mechanism described. The heading mechanism is shown in its inoperative position in Fig. 2 with the chucks retracted and in posi- Fig. 2 in the operation of heading, is the dos-- ing of the inner ends of the chuck sleeve D which is effected by inward movement of the wedge or closing rings (1 through the action of the cams D and interconnecting mechanism. Thereafter a set of can heads is delivered to the heading chucks through theslits or openingsd and the plungers or backing plates G are subsequently advancedthrough the medium of their operating cams U The advancement of said backing plates or plungers act to force the canheads with the margins of their flan as against the'annular stop shoulders d or? rings (2. The two opposingheading chucks are thereafter moved inwardly towards the: can so as to force the can heads upon the body,'which is held in axial alinementwit-h the chucks by the carrier C, the plungers or backing plates following the chucks in -this movement. After the can heads have been fitted upon the can bodies the chucks are retracted. Before the beginning of the -'retractive movement of thechucks, however,

it is necessary'to open thefacing rings (1 of the chuck sleeves to permit the ringsto pass over the head flanges or rims of the headed can. This is effected by withdrawing the closing sleeves and rings D (V, respectively,

' and when so withdrawn the slitted parts or fingers of the chuck sleeves open outwardly radially past the flanges or rims of thecan' heads. Thereafter the cross-heads are retracted through the agency of their earns 40 F and interconnected mechanism.

shoulders (1 constitute 'abutments between which and the plates G the heads are held while being forced over the can bodies, said abutments being movable radially inwardly to pass into the path of the head flanges .be-

fore the heads are pressed I over the can bodies, and move radially outwardly to clear said flanges when the chucks are retracted. The cams operating the backing plungers G are so timed relatively to the cams F that the lungers remain pressed against the can head; until the shouldered facing rings are withdrawn outwardly away" from the can heads, after which said backing plates or plungers are retract-ed until brought to the positions shown in Fig. 2, or in rear of the admission openings (1 of the chucks and therefore out of the paths of the heads next to be fed to the chucks.

' Referring now to the construction of the crimping heads and the crimping mechanism carried thereby, the same isshown more clearly in Figs. 2, 3 and 6 to 11, inclusive, and are made as follows: The crimping heads E are provided with cylindric necks E the removable facing Said.

which have bearing in openingsin the-depending removable parts E oft-he cross-- heads. Said necks are provided at their outer ends with gear wheels E (Figs. 4, 12 and '13) which mesh with gear wheels E carried by the sleeve 1) on the shaft B, whereby the crimping heads are continuously rotated during the operation of the machine. -The crimping heads are made alike and in the, following description but one head is referred to. Each head carries-a plurality of'crimping rollers E E,'four of said rollersbeing shown on each head and located at equal i distances apa t-H Each of saidcrimpin rollera is earried by a roller, stud e 'anr said .80 studs are mounted in any suitable manner upcn radially movablecrimping jaws carried by said heads. Said crimping jaws, and the means for mounting themin the heads, are

each made asfollcws(Fi s. 8,7,8,"9 andlO) i v(Figs. 8 and Q) esignates the main frame of the crimping jaw provided with -inner and outer rearwardly ,extendin arms e? a and saidframe fits within a T- aped,

radial slot inthe head which opens outwardly v I 011 the'fla't side of the head remote from the "neck i The body'of the frame is provided with a longitudinal undercut groove 6*, and

at the'bottom of said 'groovewith a longif.

tu din'a-l' depression 5. E designates a flanged block-sliding in said groove e and can in thejstud e u on which is mounted y g P one ofthe Grim ing roll Ei, the stud e extending outwar ly through the open side of its associated radial groove, l The roller stud, block E is made shorter than the main body of the frame and is adjustable radially inf 7 said frame for the'purpose of adjusting the 1 1 rolls on the head to cans ofvarying diame ters. .For this purpose, 'saidblock .is pro 19 53 yided in its inner face with a screw-threaded half-cylindric depression 6 which cooperates with the longitudinal depression a of the body of the frame to form-an opening to receive an adjusting screw E f that'has rotaI-l tive, but non-endwise movement in the frame. As herein shown, the ad usting screw is held endwise immovable 1n the fr me by a screw-stud .e (Figs. 3 and 8) fixe in 5 i5 the jaw frame near its. inner end and pro jecting into theundercut 'groove e thereof for engagement with an annular jgroove'e, at the inner end ofthe adjusting screw. The

longitudinal depression e of the jawframe- '12 fits loosely in its opeii'ifig formed-by saidgroove and the groove "of the rollerfstudf -j lock E. -The screw is pressedv against the is smooth or unscrew-threaded and the screw screw-threaded depression a ,of said block, by-rneans of a short horizontal push bar a slidingly occu ying a hor1zontal groove in the arm e of t e crimping jaw frame (Fig. 3) and projecting intothe groove ofv the frame. Said bar e 18 prov] ded with a concave, screwthreaded inner end which engages the ad V r justing screw to force the same against the screw-threads of the grooved part 'of the block E. The push bar is forced towards the adjusting screw by means of a conical adjusting stud c'-mounted in ascrew-t hreaded opening in the arm c and disposed at right angles to the push .bar. The conical inner end of said stud engages a correspondingly inclined end of said push bar (l ig. 25). When the stud is turned inwardly, therefore, it acts on thepush bar to force the latter against the screw and to hold the screw against its screw-threads. The construction described enables the. rollers to be adjusted inwardly and outwardly to correspond with cans of varying diameters, and the screw E also locks the rollers in adjusted positions. Said ,screwsare shown as provided with axial,

angular sockets 1'" whereby they may be rotated. The crimping jaws normally occupy their radially outermost positions and are shifted inwardly againstthe head flanges when brought into operative position to said cans by means hereinafter to be described.

Located centrally of each set of crimping rolls is a crimping head plate H which is adapted to be moved inwardly against the can heads at the time the crimping rollers are brought into crimping engagement with the flanges of the can heads. Each plate is shown as attached to the. inner end of a stem or )lunger H which extends outwardly through an axial opening in the neck E of the crimping head and is attached at its outer end to a depending part f of the lug l of the cross-head, whereby inward movement of the cross-head imparts alike inward movement of the crimping head plate and the crimping head. Said crimping head plate stem II is non-rotativelv fixed to the cxtensionf of the cross-head lug or arm F but is endwise adjustable with respect thereto, whereby the plate If may be accurately adjusted to the crimping rolls. As herein shown, the stem extends through a transverse opening in said depending part of the cross-head, and is non-rotatively fixed thereto by means of a screw-stud which has screw-threaded engagement with an aperture in the depending part of the cross-head and enters a key-slot or way in said stem (Fig. 1). The means for adjusting said plates If and their stems inwardly and outwardly. consists of a headed screw it that enters and l as serew-threaderl engagement with an axial socket in the end of the stem. and said adjusting screw is rotative. but endwise immovable, in the depending part ofthe cross-head. Consequently. when said screw is rotated it acts to give endwise movement to the stem H and ctnisequent movement to the crimping head plate H.

Next describing the means acting in each operation of the machine for moving the crimping jaws with the rolls thereof in engagement with the head flanges or rims of a can, when a can is properly presented thereto, said parts are made as follows: The radially outer faces of the inrer arms 0 of the gripping jaw frames are inclined as shown at 1% (Figs. 3 and 9) and said inclined faces are engaged by the oblique or inclined ends of a plurality of endwise reciprocating operating rods I I that extend throu h elongated apertures in the neck E and into the radial grooves of the heads: there being one operating rod for each crimping jaw. Said operating rods I of each set rotate with thcassociated head and are attached at their outer ends to a plate or disk 1 (Figs. 2 and 7) fixed to or made a part of a sleeve l'- which has sliding engagement with the stem ll of the crimping head plate 11. Said sleeve 1 is operatively connected with a cam .l on the sleeve 1) of the shaft B by means of a vertically swinging cam lever l' which is pivoted to a cross-pin 11 carried by fork arms f 7 on the depending partf of the crosshead (Figs. 2 and 14). When said crimp ing jaw operating rods I are thrust inwardly through the action. of the cam mechanism described, the inclined or cam surfaces 'i of said rods act upon the inclined or cam surfaces of the arms e of the crimping jaw frames to shift said jaws inwardly to bring the crimping rollers in contact with the flanges of the can head. Said opera-ting rods are shown in Fig. 3 in their innermost positions to bring their crimping jaws into their operative positions. Preferably the jaws arc radially retracted to their outermost positions by spring devices, a convenient form of which is shown and made as follows:

J J designate blocks which are interposed between the arms 0 c of the crimping jaw frames (Figs. 3 and 8) and bear'at their ends against the body of said frames and bottom of the T-shaped grooves which receive thc crimping jaws. Said blocks are provided with concaved depressions opposing the cam or inclined surfaces 0 of the inner arms of said crimping jaw frames, and in said concave depressions the rounded ends of the operating rods 1 rest and slide. Said blocks J are pressed against the rounded surfaces of the operating rods l by means of springs each of which springs bear at one end againstv the inner face of the adjacent arm c of the crimping jaw frame and occupies at its other end a socket in said block J, as shown in Fig. it will be observed. therefore, that when said operating rods are moved inwardly they operate to force inwardly the crimping jaws against the action of said springs and when said rods are retracted the springs 3 act against the outer arms 6 to retract or move radially outwardly said jaws .from. their operative positions to their inoperative positions.

The depending parts E of the cross-heads carrying the crimping heads are adjustable inwardly and outwardly with respect to the cross-heads proper, in order toproperly adjust the heading and crimping mechanisms relatively to each other. For this purpose the cross-heads are shown as provided with elongatedppenings or ways e (Figs. 3, 4'-

i and 5) in which slide the heads of the bolts e that fasten the two parts of the crossheads together, and said parts are adjusted with respect toeach other andheld 1n ad- 'uste'd relation by means of adjusting. so'rews h which have rotative, .t-i-bu-t non-endwise, movement with the parts E of said crossheads, as shown in Fig. 3, and have screwthreaded engagement with cross-bars d located in suitable recesses (1 in the crossheads proper. Byrotating said screw K in one direction or the other, the crimping mechanism .is adjusted relatively to the heading mechanism to bring the same irto -vertical valinement. 1

to support the headsand the ends of the can body when the crimping rollers are acting thereon. L

The operation of the crimpingzmechanlsm will .be obvious from the fore oing, but may be briefly stated as follows: n eachv step by' step movement ot the carrier C, a can, to

' which the heads have; been. applied, is presented. between .theop osing parts of the crimping mechanism. he first operation of the crimping mechanism is effected through the inward movement of the cross-heads which is effected by thecams li and cam levers F to move the crimping heads toward each other in=a manner to force the rolls over the flanges or rims of the can heads and upon the can (this operation occurringwhile the heading-mechanisms are being moved toward each other). Such inward movement of the 1 After this operat-ionoccurs, the crimping jaw crimping mechanism'is arrested after the rollers have been brought into line with the flanges of the can heads, as shown in Fig. 3.

operating rods I are thrown inwardly by their appropriate cam mechanisms, thereby moving-the crimping jaws radially inwardly and forcing the rolls with the desired pressure against the head flan es or rims. At the time the crim ing hea s move inwardly the crimpin hea plates H are moved against the hea s of the cans and are in such position that when the rolls are pressed inwardly against the head flan esor'rims, the margins of said plates take t 1e stress due to the inward pressure of the rolls. The crimping heads are'continuously rotated and when in contact with. the rims or flanges of the headsroll paid rims-closely on the can bodies in a familiar manner.

After the rims have been sufficientl crimped the crimping operating rods arerst retracted so as to crimping jaws to be'restoredto their radially outermost positions under the action of the springs 7' after which the cross-heads are retracted andrthereby carry the crimping heads away fromthe cans. ln the next rotative step of the carrier the can upon which the heads have thus been crimped are dis charged from the carrier chute L (Fig. 1)

being conveniently placed below the carrier to receive the cans and discharge them from the machine:

It is to be understood that the carrier and the heading and crimpin operate in such manner t at while the carrier is in, position to hold a can body to receive. a set of heads, the next advance can on the carrier ispresented to the crimping permit the mechanisms 00- .mechanism and further that the heading and crimping mechanisms'operate simultaneously when the carrier is at rest.

It will be noted: that the connection of the cross-heads with the sleeves b on the shaft B, by means of the arms e as described, act, when the cross-heads move inwardly or outwardly, to correspondingly shift the cams D and I as well as the gear wheels E Inasmuch asthe levers D and I are ivoted on the cross-heads and the gear whee s E of the crimping heads are movable with the crossheads, the. inward and outward movements of the cross-heads have no effect on the relative movements of the parts actuated by the cams D and I and gear wheel E Any suitable mechanism may be employed to intermittently rotate the carrier C to successively bring the can bodies inoperative position relatively to the heading and crimpmg mechanisms inthe manner stated. The

meansherein shown for effecting such intermittent rotative movement of the carrier in its construction 'embraces a Geneva stop movement. It comprises a continuously rotating shaft M (Figs. 15- and 16) which is rotated. from the power shaft B through the medium of a gear wheel M, herein shown'as aflixed to the cam F (Fig. 2), a gear wheel M3 fixed on the shaft M, and an intermediate gear wheel M meshing with the gears M and M and mounted on a shaft m fixed to the rear wall of the hollow base.

The shaft M carries at its inner end a disk amass M provided with a laterally extending stud m which engages the radial grooves c of a wheel Cf, fixed to the shaft of the rotative carrier C, whereby the whe'el'shaft and carrier are rotated'one ste during each rotationof'theldiskMQ The w eel C and carrier are I I hel d.atirest during that portion of the rota' tion of the disk in which the stud'm is out ofengagement with the grooved wheel byengagement ofan annular surface m on said i disk, Withconcave de ressions a 'on the peripheryaof the wheel between the grooves.
